I have this strange circular bruise type thing on my front thigh. Its a light purple. I have noticed it for a couple of weeks and it does not change in color. Nor, does it have any pain to it whatsoever. There isn t any opening wounds near it or on it. Tonight, when i was in the shower, I noticed it was extremely more noticeable in color and shape, so i believe the hot water brings the blood up to the surface of my skin and makes it stand out more.. But, I am really getting concerned as to what this could be. Please help! Thank you!
